MACHINE FOR DYEING SKINS.

SPECIFICATION forming part of Letters Patent No. 765,375, dated July 19,1904.

Application filed ctoher30, 1903. Serial No. 179,172. (No model.)

To (ZZZ whom) it 71200; concern.-

Be it known that I, PIERRE BRUFFAERS, manufacturer, a subject of theKing of Belgium, residing at Schaerbeek, Belgium, have invented a newand useful Machine for Dyeing Skins; and I do hereby declare thefollowing to be a full, clear, and exact description of the same.

The present invention has for its object a machine for dyeing skins.

In. the annexed drawings is represented, by way of example, a form ofconstruction of the object of the invention.

Figure 1 is a side elevation, partly in section. Fig. 2 is a frontelevation. Fig. 3 is a plan.

According to this invention the shafting 1, on which the fast and theloose (2) pulleys are fixed and over which the belting coming from theengine travels, controls the two pulleys 4 and 5 by means of the pulleys6 and 7, one of which is fixed and the other of which is loose on shaft1, and the belting 8, which passes through the openings 9 of theframework 10. The pulleys 4 and 5 are keyed on the axles 11 of theface-plates 12, placed one above the other. In the annexed drawings onlytwo face-plates are represented; but in reality any number may be addedand a rotary movement imparted to each one by transmitting such movementfrom the shafting 1 by means of any of the several mechanicalcombinations used for this purpose. The shaft 1 might, for instance, bemade to turn a vertical shaft containing as many pulleys as there arefaceplates, each one of these pulleys controlling separately each one ofthe face-plate pulleys. The face-plates 12 may be either quite flat orslightly convex. Each one of the face-plates 12 is supported by across-piece 13, keyed on the axle 11. A face-plate can'thus be takenofi? or replaced with the utmost ease. Each The slide-rod 17 has a slot19,

into which slips the catch 20 when the sliderod 17-is in such a positionthat the belt runs on the fast pulley. The catch 20 is connected by arod 21 to a lever 22, turning on an axle 23. This lever 22 can at anygiven moment be raised by a pin 50, fixed to the wheel 24, whichreceives a rotary motion by means of the wheels 25 and 26 and the worm27, attached to the shaft 1. When this lever 22 is raised, it lifts atthe same time the catch 20, which releases the slide-rod 17, and thebelt is brought back onto the loose pulley 2 by means of thecounterpoise 28, which is suspended to the slide-rod 17 by the wire rope29, passing over the pulley 30. To this sliderod 17 is attached an arm31, working in the socket 33 of another lever 32, connected to the crank34. This crank 34 is connected to a socket 35, provided with as manyfixed tubes 36 as there are face-plates 12. In the position representedin the drawingsthat is to say, when the machine is at restthe tubes 36have their upper extremities opposite the solid parts of the head onwhich the socket 35 turns and their lower extremities above the annulargrooves 14. When the machine is set in motion by pulling slide-rod 17,the crank 34 turns the socket around, so that the upper extremities ofthe tubes 36 are brought exactly opposite holes drilled in the head onwhich the socket 35 turns and are therefore put into communication withthe dyeing-tank 37, while the lower ends of the tubes are caused to moveto a point approximately above the centers of the plates 12.

The annular grooves 14 are joined together by the tubes 38. The lowergroove is con- "nected by means of a pipe 39, .furnished with athree-branched cook 40, on the one hand with a blow-off pipe 41 andonthe other with a receptacle 42. This receptacle 42 is in its turnconnected by a pipe 43, furnished with a threebranched cook 44, with ablow-off pipe 45 on the one hand and a force and suction pump on theother. The pipe 47 from the forcepump dips into the upper part of thedyeingtank 37. The pump 46 is worked by means of a rod 48, attached tothe eccentric 49, fixed on the main driving-shaft 1.

The working of the machine is as follows: I

A workman stretches a skin on each of the different face-plates and thenplaces the plates on the cross-pieces 13. He pulls the slide-rod l7, andthe machineat once gets into motion. The dye issuing from thedyeing-tank 37 comes into contact with the skin and as a consequence ofthe centrifugal force spreads itself over the whole surface of the skinslaid on the rotary plates 12. The surplus dye runs away into the grooves14:. hen the wheel 24 has completed a revolution, the pin 50, which canbe adjusted in a radial slot 51 in the wheel, engages and lifts lever22, consequently lifting catch 20, and so releasing the slide-bar,whereby the driving-belt is shifted from the fast to the loose pulley.While the machine is running the workman employs his time in preparingand fixing other skins on supplementary plates, which take the place ofthose taken off the machine and which in their turn are subjected to theaction of the dye. The dye which has accumulated in the grooves is run01f into the receptacle42; but in order that this dye shall not getmixed up with urine or other corrosive substance the blow-off pipe ll isfirst opened and a certain quantity of the dye escapes, carrying alongwith it the urine or corrosive products. The communication with thereceptacle is then established. As

soon as the machine is set in motion again the force and suction pump4C6 draws off the dye collected in the receptacle 42 into the tank 37.

Fresh dye can be introduced into the tank 37 either continuously or atintervals, at will.

This dyeing-machine offers numerous advantages. It realizes aconsiderable economy in labor. It dyes at a single operation as manyskins as there are plates. The plates being easily changed, the timelost by the stoppage of the machine is reduced to a minimum.

I declare that what I claim is- In a machine for dyeing skins, thecombination of the frame, a rotary drive-shaft ar ranged therein, fastand loose pulleys arranged on said shaft, a belt-shifting slide-rodarranged in operative proximity to said pulleys, the same having a notchtherein, means for normally holding said slide-rod at one of its limitsof movement, a pivoted catch engageable with said notch, holders onwhich the skins are maintained extended, means for transmitting powerfrom the drive-shaft to said holders whereby to rotate the holders,means for discharging the dyeing materials onto the skins while so held,and means, actuative from the drive-shaft, for automatically moving saidcatch and thereby releasing said slide-rod, substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
